A changeable start to the period with low pressure near to the UK bringing periods of rain and strong winds. The wettest and windiest conditions are likely to be across the northwest with perhaps some decent drier interludes across the south and east. Around the turn of the month or into early November, wetter and windier conditions across the north and west are likely to extend more widely across the country. The detail is somewhat uncertain but it is likely that low pressure becomes established to the west of the UK allowing bands of rain to spread across the country at times. Temperatures perhaps little below average at the start of the period, but likely trending upwards with potential for a mild spell around the turn of the month.
